Arroyo listed on Salem-Keizer roster

The San Francisco Giants short-season affiliate, Salem-Keizer, announced its 2014 roster Tuesday, confirming a first-rounder and recent Augusta GreenJacket will play there.

Infielder Christian Arroyo, drafted 25th overall in 2013, is on the Salem-Keizer roster as the Volcanoes begin their season Friday.

Arroyo played 31 games for the GreenJackets to begin the 2014 season, struggling to a .203/.226/.271 line and five extra-base hits in 125 plate appearances. He played the majority of the time at second base and did well there, which was perhaps the one bright spot in his initial taste of full-season ball.

Arroyo went on the disabled list in early May with a sprained left thumb. There was no structural damage. He was sent to Arizona to rehab the injury and has been playing every day in extended spring training. The talk over the past few weeks has been sending Arroyo to Salem-Keizer when its season opened, and this has been officially confirmed.

When Arroyo will return to Augusta is unknown. He's only 19 years old and could use time in short season as a mental break while working on his hitting.

Right-handed reliever Ray Montero is officially on a rehab assignment to Salem-Keizer along with Arroyo. Montero gave up eight earned runs and 10 total in 11.1 innings for the GreenJackets earlier this season.
